I don't know if this will ever happen but do any of the people here avoid using warhammer and maces because of their finishers?

I agree with you. They clearly favour the blade/sword. It has by far the most finishers in the game. There should be more with the axe and mace type weapons in my opinion. There should also be more with hand-to-hand. That includes creatures etc,not just human enemies.

whats wrong with them?
dont you like the headbutt finisher?

There should be more. I like the headbutt one. But swords clearly have the most,and probably the most stylish. OP has a point.

the fact that sword have more doesn't bother me.
since people tend to use swords more afaik.
do we have a number on how many mace finishers there are compared to swords?

I don't have an actual number,but going off human enemies,the sword clearly has way more...especially with one-handed. With a one handed mace or axe you mainly smash them to the ground,or the upper cut like swing...that seems to be it for them. The one handed sword however does lots of different ones.

perhaps this would help?

I don't. I turned all killcams off, so it's all the same to me.

I think some of them are wrong. The war axe does not do some of the moves it says on there. Either way,blades have by far the most when it comes to variety.
